Function of the microbiota
(Elsevier Sci Ltd, Oxford, 2013)
The gut microbiota of humans is complex but stable in composition and function. Metabolic conversions performed by the members of the microbiota yield both beneficial and hazardous compounds, and have a systematic impact ...
Modeling of Fischer-Tropsch Product Distribution over Fe-based Catalyst
(Aidic Servizi Srl, Milano, 2013)
The kinetic models of Fischer-Tropsch synthesis (FTS) product distribution can be classified into two major groups: hydrocarbon selectivity models and detailed Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic models. In ...
Toward Optimum Working Fluid Mixtures for Organic Rankine Cycles using Molecular Design and Sensitivity Analysis
(Amer Chemical Soc, Washington, 2013)
This work presents a Computer-Aided Molecular Design (CAMD) method for the synthesis and selection of binary working fluid mixtures used in Organic Rankine Cycles (ORC). The method consists of two stages, initially seeking ...
Raman spectroscopy of bismuth silicon oxide single crystals grown by the Czochralski technique
(IOP Publishing Ltd, Bristol, 2013)
In this work, single crystals of bismuth silicon oxide (BSO; Bi12SiO20) have been grown by the Czochralski method. The growth conditions were studied. The critical diameter and the critical rate of rotation were calculated. ...

Coexistence of several sillenite-like phases in pseudo-binary and pseudo-ternary systems based on Bi2O3
(Elsevier, Amsterdam, 2013)
A series of polycrystalline samples containing sillenite-like (doped gamma-Bi2O3) phases were prepared by high-temperature reactions from alpha-Bi2O3 powder and different oxides in six pseudo-binary Bi2O3-MxOy (M = Mn, Ti, ...
Experimental measurement and modelling of viscosity of the binary systems pyridine or nicotine with polyethylene glycols at T = (288.15-333.15) K. New UNIFAC-VISCO and ASOG-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2013)
Viscosities of four binary mixtures: pyridine + PEG200, pyridine + PEG400, nicotine + PEG200 and nicotine + PEG400 have been measured in temperature range 288.15-333.15 K with temperature step of 5 K and at the atmospheric ...
Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
